The 2nd edition of Research.com ranking of the best scientists in the
arena of Materials Science is based on data
combined from multiple data sources including OpenAlex and
CrossRef. The bibliometric data for estimating the citation-based metrics were
gathered on 21-12-2022. Position in the ranking is based on a
scholar’s D-index (Discipline H-index), which
only includes papers and citation
metrics for an examined discipline.

The scope of our Materials Science research
Research.com’s best researchers ranking is a credible
account of leading scholars from the area of
Materials Science, created using a detailed
analysis of 166,880 scientists determined
from various bibliometric data sources. For the discipline of
Materials Science, over 17130 researchers were
analysed.
What is D-index acceptance threshold for Materials Science
The D-index threshold for accepting a scientist to be
examined is set to 40 if
most of their publications are in the area of Materials Science. The
approval criteria for scholars to be
considered into the ranking of top scholars are based on the D-index, ratio
of the contributions made within the selected area
in addition to the awards and achievements of the scholars. The
D-index threshold for including best researchers is
set as an increment of 10 depending on the total number of researchers
assessed for each area od study whilst
guaranteeing that the top 1% of leading researchers are
considered into the ranking. We estimate a proximity of
30% or less between a researcher’s general H-index and their D-index.
Other verification practices
Since our leading mission is to make sure that only
genuine scientists are listed in
Research.com ranking we believe that raw data are never
meant to be a full means to quantify the
contributions of scientists. Because of that
we manually check every profile and cross-correlate it against publications in a
wide range of reliable sources. While it’s not a
metric defining a researcher’s position in
our ranking, the amount of documents published in
prominent journals and conference proceedings should constitute a
reliable secondary implication of their contribution to research in a
selected area of science. Position in the ranking is
based on every scholar’s D-index
using data compiled from OpenAlex and
CrossRef, which are the most trustworthy and well-known bibliometric
databases of this type accessible to the scientific community. A
detailed explanation of our research procedures
can be found on our
methodology page.
Our mission
Our objective is to motivate scientists,
entrepreneurs and administrative bodies
worldwide to investigate where top experts are heading
and to give an opportunity for the entire scientific community to
discover who the leading experts in specific
areas of study, in various countries, or even within research
institutions are.
